Handling Precautions Introduction This product is to inspect (discrimirate/measure) sensing objects. Never use this product for prevention of accidents which damage a human life or properties or for safety maintenance. WARNING Connection The GP-X series is configured to satisfy the specification with the combination of the sensor head and the controller. Use the sensor head and controller in combination without fail; with other combinations, not only may the specifications may not be satisfied but also failure may result. Turn the controller off before mounting or removing the sensor head and controller. Note that the cables will be damaged if they are pulled. Power Supply Wait 15 minutes (or 20 minutes with GP-X3S and GP-X5S) after the power is turned on before operation is started. There may be a variation in the measurements immediately after power-on because the power circuit is not stable. There is a muting time of about two seconds after the power is turned on. Take care that wrong wiring may damage the sensor. Verify that the supply voltage variation is within the rating. If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground. Make sure to use an isolation transformer for the DC power supply. If an auto-transformer (single winding transformer) is used, this product or the power supply may get damaged. In case a surge is generated in the used power supply, connect a surge absorber to the supply and absorb the surge. Wiring Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction. Make sure that the power supply is off while wiring. The analog voltage output is incorporated with a short circuit protection circuit. Do not connect it directly to a power supply or a capacitive load. Be careful to avoid statically charging connectors during wiring work. A failure may result. Use the exclusive extension cable for cable extension of the sensor head. (Overall length: 10m) 2

Environment This product has been developed / produced for industrial use only. Avoid dust, dirt, and steam. Take care that the sensor does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc. In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground. Take care that stress is not directly applied to the cable joint. This sensor is for indoor use only. Introduction Compatibility In case the sensor head is broken, the sensor head replacement is possible with same model.

1.7 Connection 1.7.1 Connecting the Sensor Head and Controller While holding the ring around the connector of the sensor head, insert the connector into the sensor head connector of the controller until it snaps. Chapter 1 Controller Sensor head cable length selection switch Upper side: Standard (3m) + extension (7m) Lower side: Standard (3m) (Factory shipment setting) Sensor head connection connector Ring around connector POINT To disconnect, hold the ring around the connector and pull straight toward you. Notice Turn the power off before connecting the sensor head to the controller. Check before turning the power on. The circumferential ring of the cable connector is connected to 0V. When using an extension cable, take measures to isolate the connector so it does not make contact with any surrounding conductors (metal). Check that the setting of the sensor head cable length selection switch is consistent with the cable length, before turning the power on. The controller will not correctly recognize the cable length with a wrong setting. When using an extended cable (GP-XCCJ7; cable length 7m) to extend the sensor head cable length, slide the sensor head cable length selection switch up. After operating the selection switch, turn the power on again and perform calibration at three points without fail. Do not pull the cable; otherwise the cable will be damaged. 19

Zero Setting Chapter 2 Press and hold the key on the panel for longer than two seconds to change the current position of the detected object to the zero (reference) position while the displayed value and analog voltage output are zeroed. Use this key to adjust the reference position according to a slight difference in the detected object or according to the workpiece positions varying as time passes. Press and hold the key for longer than two seconds, too, to cancel zero setting. Press and hold for longer than two seconds. Press and immediately release the ON/OFF state. key to check the current zero setting Zero setting ON Zero setting OFF If scaling is set, the offset at a detected distance of 0mm is displayed when the key is pressed. If the detected distance exceeds the detection range (maximum detection distance), zero setting cannot be performed. If zero setting is attempted, an "Err15/0-Set" error message is displayed with an alarm output. After pressing and holding down the key for two seconds to remove the error, set the distance again, within the detection range. Make sure to check the trigger level (in the case of internal trigger) and the upper and lower limits after zero setting. Zero setting can be performed from an external input terminal. Zero setting cannot be reset from an external input terminal. 28

Notice Turn on the panel key lock function to protect the memory if zero setting from the external terminal is used frequently. (The maximum memory writing frequency is 100,000 cycles.) *To perform zero setting, set the detection distance within 1/2 F.S.
